Texas Instruments TL33074DW

Overview

TL33074DW from Texas Instruments is a quad operational amplifier designed for industrial and automotive signal conditioning, featuring 4.5 MHz gain-bandwidth product, 13 V/µs slew rate, −40°C to 105°C operating temperature range, ±2 V to ±22 V supply voltage capability, and rail-to-rail input common-mode range including ground (VCC−). It delivers low 0.02% THD at 10 kHz and supports high-capacitance loads up to 10,000 pF.

For engineers reviewing the TL33074DW datasheet, TL33074DW pinout, TL33074DW application, or TL33074DW equivalent, key selection considerations include its industrial-grade temperature rating, Darlington-input stage enabling low 3 mV max input offset voltage, all-NPN output stage with symmetrical source/sink drive, and compatibility with single- or dual-supply configurations in precision analog front-ends.

Technical Context

The TL33074DW employs a Darlington transistor input stage delivering high input resistance (150 MΩ) and low input bias current (−0.7 µA typ), paired with an all-NPN output stage that eliminates crossover distortion and enables large output voltage swing (−14.7 V to +14 V with ±15-V supplies). Its internal compensation ensures stable operation with 60° phase margin and 12 dB gain margin under no-load conditions.

It supports wide-range single-supply operation from 4 V to 44 V total supply, with input common-mode voltage extending to VCC− (ground in single-supply mode), making it suitable for sensor interface and active filter circuits where ground-referenced inputs are required without level-shifting.

FAQ

What is the maximum supply voltage for TL33074DW?

The TL33074DW supports a total supply voltage range of ±2 V to ±22 V, meaning it can operate with dual supplies up to ±22 V or single supplies from 4 V to 44 V. Absolute maximum ratings specify VCC+ ≤ +22 V and VCC− ≥ −22 V; exceeding these risks permanent damage. For reliable long-term operation, TI recommends staying within the recommended operating conditions of ±2 V to ±22 V across the full −40°C to +105°C temperature range.

Does TL33074DW support single-supply operation with ground-referenced inputs?

Yes, the TL33074DW supports true single-supply operation with input common-mode voltage range extending to VCC−, which is ground when configured for single-supply use (e.g., VCC+ = 5 V, VCC− = 0 V). This allows direct connection of unipolar sensors such as thermistors or bridge outputs without external biasing networks, simplifying front-end design while maintaining accuracy across the full industrial temperature range.

What is the input offset voltage specification for TL33074DW?

The TL33074DW is offered in standard and A-suffix grades. The A-suffix version guarantees a maximum input offset voltage of 3 mV over the full −40°C to +105°C operating range, while the standard grade specifies 5 mV max. This parameter is measured at VCC± = ±15 V and is critical for precision DC-coupled applications such as strain gauge amplification or medical biopotential signal conditioning where minimal baseline error is required.

Can TL33074DW drive heavy capacitive loads without oscillation?

Yes, the TL33074DW is characterized for stable operation with up to 10,000 pF capacitive loads, as confirmed in the datasheet's operating characteristics table. Its internal compensation and 60° phase margin at no load (reducing to 40° at 300 pF) ensure robustness in applications such as LCD bias generation, piezo actuator driving, or long-cable transmission where output capacitance exceeds typical PCB trace values.

Is TL33074DW pin-compatible with other industry-standard quad op-amps?

Yes, the TL33074DW is pin-compatible with the MC33074, MC34074, and MC35074 families in the 14-pin SOIC (DW) package. This compatibility enables drop-in replacement in existing designs, particularly those targeting industrial temperature ranges. The pinout matches the standard quad op-amp configuration: 1OUT, 1IN−, 1IN+, VCC+, 2IN+, 2IN−, 2OUT, VCC−/GND, 3OUT, 3IN−, 3IN+, 4IN+, 4IN−, 4OUT - verified in the official TI datasheet SLOS097C.
